摘　　要：在专家(利益相关者)数量较多的群体评价中,为了尽量体现各方案(或被评价对象)之间的差异,而又得出群体可接受的一致性结论,提出了一种兼顾差异性与一致性的大规模群体评价方法.首先在最大限度体现方案间差异的基础上,以差异稳定为依据进行群体意见类别划分,以保证同一意见类内不同专家之间评价结论的一致性;然后以"类影响力"为依据进行类间信息的集结,以得出一个群体可接受的一致性结论.最后给出了一个应用例,说明了方法的有效性.For a mass evaluation which is carrying out with a large number of experts （stakeholders） participating in it, a method is proposed to balance the discrepancy and consistency in evaluation results, representing diverse alternatives to highlight the discrepancy as much as possible and reasoning out a conclusion in which the consistency will be acceptable to all participants. In this method the discrepancy between different alternatives is enabled to the utmost extent and all the alternatives are divided according to the stabilized discrepancy, thus ensuring the consistency of evaluation results that were given by different participants whose alternatives were of the same category. Then, the information between different categories are aggregated according to the generic influence so as to reach a conclusion of consistency acceptable to all participants. An application example is given to illustrate the validity of this method.
